问：weaken the evidence
evidence: the more social contact, the better mental skills.前者影响后者，两者呈正相关
两个角度考虑削弱：1后者影响前者（mental影响social）  2第三因素导致
B选项有两种理解方式，结合上面的两个角度分别是：
1Medical给mental带来消极影响，这种影响引起social isolation（mental影响social 这里Medical不重要）
2Medical给mental带来消极影响的同时，增加了social isolation（Medical作为第三因素同时影响mental和social）
个人更倾向于后者的理解，因为B中的句子结构medical blabla是作主语发出affect和tend to increase两个动作的。
其实考试的时候因为时间有限无论哪种思考方式都OK，体会出削弱作用就足够了。

另：这里的social和mental没有很强的因果关系，只能说是影响关系。而且非要取the more...,the better...的逆否命题也应该是not the better...,not the more...而不是the worse...,the less...

请问E选项为什么不对？不可以这样理解吗？就是说这项研究表明提高mental sharpness 是因为 数学问题导致的 ...

同问，我也是这样认为的啊

因果倒置削弱法，evidence表明：社交越多，精神越好。那么因果倒置削弱之：精神越好，社交才越多，同理，精 ...

精神越好，社交才越多，为什么可以推出精神不好，社交也不好？这不是等价的吧，就好像说A cause B 成立的情况下并不能推出 not  A cause not B 吧

因：Social contact上升然后mental skill上升果：social interaction是sufficient的答案必须同时提及Social ...

我觉得helr这个题讲的说服力并不强

Gmat Club上看到的一个言简意赅且有说服力的解释。
The conclusion states that social contact improves mental skills. This could be true regardless of how mental skills are tested. Perhaps social contact improves performance on math problems.

看了这么多大神的解释，终于从一头雾水到开始懂了一点，非常感谢。前面对b的解释已经非常清楚了，我想再贴一个对e的理解。来自gmatclub的@gmatninja

We are trying to determine whether participating in social interaction (i.e. talking to other people) engages many mental and perceptual skills and thus helps people maintain mental sharpness as they age, just as solving crossword puzzles or mathematics problems does. The evidence in support of this theory is that the more social contact people report, the better their mental skills.

Quote:
(E) The tasks evaluating mental sharpness for which data were compiled by the study were more akin to mathematics problems than to conversation.

According to the study, if you had more social contact, then you generally had better mental skills. But how were those mental skills measured? What if the tasks used to evaluate mental sharpness were more akin to CONVERSATION than to math problems? All that would show is that people with more social contact are better at conversation (duh!). That doesn't really support the idea that social contact can REPLACE math problems and crossword puzzles as a way to maintain mental sharpness.

However, what if the tasks used to evaluate mental sharpness were more akin to MATHEMATICS problems than to conversation? That would suggest that social contact COULD replace math problems as a way to stay sharp. In other words, you don't NEED math problems to stay sharp with mathematical tasks. Rather, you could use social contact to stay sharp with mathematical tasks. That could strengthen the argument.

I hope that helps!

mark一下，因果的一个削弱，就是果发生了因
